[Es2] things that tend to break on es2's at the track

The 2bennett radiator is the same as the Dialynx UrQ radiator, which 
I believe is actually made by someone in Germany

034 Motorsport actually carries two versions of the radiator, and 
another developed as stock plug and play ( and priced that way too)
